Front wheel turning degrees

The Freightliner Columbia, do you think it has 45 DEG----or 50 DEG turning angle on the front tires? And what is norm for a TC, thanks Gene.

My son drives over the road. He's got a company truck, an '05 Columbia. I just called him, he's on his way from Montreal to Iowa right now. Anyhow, he said he would guess they turn even more than 50 degrees. He hasn't ever measured it but he said they turn pretty far. He's not going to be stopping until 2330 tonight and I don't think he wants to get out and try to measure it. He thought maybe you could find the spec somewhere on line. Maybe tomorrow he'll crank it all the way over and try to guess the angle. I don't know how you'd measure it. How would you without any fancy guage or something?

I'm wondering when they'll figure out how to get a 90 deg. cut angle; that way you should be able to parallel park your rig with one hand(the other occupied with the, uhhh, beverage of choice) into a space a couple of feet longer than the rig. Now THAT would be progress........ But then I've seen it tried with existing rigs, with embarrassing results........

the buses have 4 wheel steering available now. that helps tremendously. I believe the bogey wheels are computer controlled.

Powerhouse Coach (the one in Idaho) has a lateral drive option on their rigs. Go here: http://www.powerhousecoach.com/video.html and you'll see their videos. Pretty cool but I don't think it's worth $20k. I don't know if they're even in business anymore. Looks like their web site was last updated in '08.

I would assume* that since the website still exists (SOMEBODY is paying for it) they must still be around. I wouldn't have one of those overgrown behemoths(my opinion). They are mainly a 5th-wheel coach mounted on a truck chassis, and many are too long to register in some states.

*dangerous word...to assume makes an ASS outta U and ME;-)
